Working Theory

Thanks to the unique and patented 360-degree electrode design, higher engine horses, awesome engine response and wondrous vigor are attained through better fuel energy utilization. These Polaris Xplorer 400L racing series spark plugs are designed to help you improve power, low-end torque, launch time and acceleration to further increase fuel economy. Our four-wheeler Polaris Xplorer 400L racing series spark plugs' design ensures optimum mix ignition in the cylinders and warrants more performance level compared to traditional projective tip sparkplugs and other brand quad performance plugs. The 360-degree electrode Polaris Xplorer 400L sparkplugs outperform even the iridium sparkplugs in regards to firing energy, extra performance potential as well as longevity. While traditional fourwheeler plugs’ constantly thriving deposits spoil the spark discharge, no soot will be deposited on 360-degree fourwheeler spark plugs’ electrodes, because throughout the life of the spark plug the gap size remains as it was originally, apart from normal wear and tear. Because the plug gap is not shielded by the conventional side electrode, exposing the mixture to physically unlimited ignition, combustion speed will increase and flame front spread can take place more easily, and especially more quickly. Easy engine start is attributed to this effect. The subsequent increase in medium effective pressure within the engine cylinder also contributes to extra engine performance and optimum quad fuel efficiency. These Polaris Xplorer 400L multi-spark spark plugs are made for extreme operating conditions and high output; there is simply no competition for the Brisk 360-degree plugs.

360-degree electrode design provides an unrestricted full potential spread of the flame front, which is accomplished by a state-of-the-art retracted ground electrode. Unlike ordinary plugs, where discharge is constrained by the ground electrode, Brisk Polaris Xplorer 400L racing spark plugs feature an electrode layout where the ground electrode is retracted, so the spark discharge occurs at the very tip of the spark plug. Traditional spark plugs' ground electrodes restricts the natural spherical expansion pattern of the flame front whereas our High Performance Polaris Xplorer 400L sparkplugs take the advantage of surface spark discharge, along with retracted ground electrode designed, to ensure max spark exposure and unrestricted flame front expansion. Due to stronger spark discharge, a spark can more easily trail along the surface of the insulator than having to break through the air gap. Roughly 70% of the spark travels between the electrodes along the surface of the insulator, also bear in mind that the spark front line is drawn on the whole perimeter of the ground electrode in 360-degree, thus the volume of the spark discharge is maxed out, while not requiring much higher ignition energy supplied by the ignition system. Therefore this ATV Polaris Xplorer 400L racing spark plug works conjointly with stock ignition and no upgraded coil or performance ignition lead is mandatory accordingly. 360-degree multi-spark sparkplugs use the highest quality materials, are produced in European state-of-the-art manufactories and in a never-ending effort to improve upon success, Brisk has also developed electrode technology that is far superior to all others in function and form.

The protruding compact electrode design concentrates the spark deeper in the chamber, ensuring fully symmetric and effective spark discharge in the combustion chamber without any undesired turbulence, which is common on traditional projective tip spark plugs and which in fact negatively affects volumetric flow. Our dyno-proven Polaris Xplorer 400L high-power plugs give some extra performance level besides reducing fuel consumption thanks to the state-of-the-art, 360-degree, round electrode. When designing a plug, several technical factors must be taken into careful consideration. Yet during the engineering phase Brisk decided to merge new technology which leaves all other spark plugs outdated. These Polaris Xplorer 400L high-power spark plugs are the only specified performance multi-spark sparkplugs in existence. Their lifespan is 25K miles - 40K km or 500-600 hours. In the long run they pay for themselves.

Brisk’s patented 360-degree spark plug electrode design improves upon the phenomena that caused racers to cut ordinary electrode spark plugs in order to increase the number of sharp edges and improve the spark discharge. Given the short time interval for combustion to occur, engineers have always known that the faster you can get the flame to the piston from a spark plug, the better. The more quickly the flame kernel travels toward the combustion area, the better. The 360-degree design is actually open all around, so the spark travels directly toward the air-fuel mix which enhances the burn. The end result is a faster flame kernel, a more complete combustion, added performance potential and higher fuel consumption on your Polaris Xplorer 400L. All around the best designed sparkplug for Polaris Xplorer 400L enthusiasts looking for a replacement sparkplug; the latest technology used in our racing sparkplug allows for increased fuel consumption by as much as 5% by ensuring reliable combustion events all while delivering smooth engine operation, added power output and driving characteristics over other spark plug electrode designs.

Installation Instructions

It’s time to tune up your quad’s ignition, so assumingly first you head to surf search engines seeking the best high-power plug. In most cases, you’ll see at many different types of spark plugs, from different manufacturers. Will it be Copper, Platinum or Iridium spark plugs? How do you know which are the best spark plugs to purchase? Simple. Pick that one has the most persuasive working theory on achievement of your performance level wise goals. We are reluctant to believe, you will ever find better performing plug on the market over these Brisk performance plugs.

throttle response is smoother

I would definitely recommend thia super plug. It is not a pain to install like (removed) plugs and after getting it in it work great. I didn't see very much difference in riding or anything but my old plug was black when I changed it out and throttle response is smoother, cold start became easier.

did feel the torque in the seat

I cant confirm the figures increase going from factory to this plugs but i did feel the torque in the seat thats for sure. MPG's seem to increase too. very happy with my plugs and certain I recommend this to friends i know and wish they made this for every vehicle. Rest assured excellent spark plugs for your bucks.

they work unbelievingly fine

Got these 360 plugs from (removed) and they work unbelievingly fine. They are a bit over priced, but thanks to price matching policies in place, we got a good deal on a set of 8 plugs taken by my outlander fellows.

I did find real difference

I've used NGK and Denso plugs in my metric race bikes and street, trail quads for over 20 years. NGK spark plugs have always preformed perfectly. When I stumbled across these overhyped plugs I was in the opinion why pay more for heavily advertised brands? Finally I've tried magnum power spark plugs and I did find real difference. Better hp improved mileage and gallon/hour consumption. What more could you expect??

Great ptoduct

I upgrade my Brute with multi spark high performance spark plug and i notice extra amout of tork during climbing high and steep hills over Pa summits. I love this spark plugs and i stay with them for ever. Martin

spark and work well

What can I say, brisk racing series spark and work well although they’re higher priced than many other brands. Great product. Shipping speed could be improved however. Bottom line: I’d recommend this to a friend
